Embodiment

[0037] A production method of a die-cut piece containing acetate cloth, such as Figure 8 , the acetate cloth 3 comprises horizontal and vertical well-shaped weaving patterns, and the method comprises the following steps:

[0038] (1) The bonding of the first-level material tape: the release film 2 and the acetate cloth 3 are sequentially bonded on the protective film 1 to form a first-level material tape;

[0039] (2) Die-cutting waste disposal: such as figure 1 , Die-cut the primary material belt in a die-cutting machine, and discharge a punching waste to form a secondary material belt; such as figure 2 , a die-cutting machine is provided with a knife line a that matches a die-cutting pattern, such as image 3 , the punching level of knife line a is acetate cloth 3. Cut line a includes cut lines a connected in sequence 1 , knife line a 2 and knife line a 3 , knife line a 2 At an angle of 30° to the running direction of the material belt. knife line a 1 and knife l...

Abstract

The invention relates to a manufacturing method of a die cutting piece containing acetic acid cloth, the acetic acid cloth (3) comprises #-shaped weaving lines which are arranged in a transverse and vertical alternate mode, and the manufacturing method is characterized by comprising the following steps that (1) a first-level material belt is attached; (2) primary punching die cutting and waste discharging; (3) secondary punching die cutting waste discharge is conducted, specifically, secondary punching die cutting is conducted on the second-stage material belt on a secondary punching die cutting machine, secondary punching waste is discharged, a finished product of the acetic acid-containing cloth die cutting part is formed, a cutter line b matched with a secondary punching die cutting pattern is arranged on the secondary punching die cutting machine, the cutter line b comprises a cutter line b3, the included angle between the cutter line b and the running direction of the material belt ranges from 30 degrees to 60 degrees, and the cutter line b3 is located on the side where waste is discharged first; and (4) rolling the die cutting piece product. Compared with the prior art, the method has the advantages that broken filaments cannot be formed on products, and the reject ratio of the products is low.

Description

technical field [0001] The invention relates to the field of die-cutting parts processing, in particular to a method for manufacturing a die-cutting part containing acetic acid cloth. Background technique [0002] Because the acetate cloth substrate has strong moisture absorption and breathability, good resilience, easy to wash and dry, no static electricity and hairball, and excellent aging resistance, it can last for more than 15 years. At the same time, the acetate cloth tape processed from the acetate cloth base material has the characteristics of high temperature resistance, anti-aging, soft and compliant, good conformability, easy punching, easy unwinding, acid resistance, alkali resistance, mildew resistance, etc., and excellent insulation performance. In general glass fiber cloth and glass cloth, it is widely used in TV, transformer, air conditioner, computer and other manufacturing fields. [0003] And it is often used in the interlayer insulation of motors and tra...
